RAILS for a ML370T01 Need Help

I have a ML370T01 server that I am trying to put in my "Round Hole" server rack. I don't have any rails and they are hard to find. I found someone selling this with the desription: 149068-B21 Compaq Genuine Tower to Rack Conversion Kit Proliant 1200 1600 2500

I have 2 pictures of the server and one picture of the "conversion kit" do you think it will work. I am not sure if mine is a 1200, 1600 or 2500 or something else.
